ACTION REQUIRED

We are pleased to announce the availability of a new file system (/work2) on new upgraded hardware. Users must migrate any current data they wish to keep from /work to /work2.  Users should complete the migration before 17 May 2021 when /work2 becomes the only work file system mounted on compute resources. As of 19 April 2021, /work will become read-only, and thus all file writes will need to go to /work2. Note that /work is NOT backed up, so you MUST migrate your data to /work2 if you wish to keep it. A more detailed timeline and technical details on how to most efficiently accomplish migration can be found in the  /work Migration and Transition Guide.

Prior to migrating data, users are encouraged to review their data to identify that which can be deleted. The Ranch Archive Facility is also available for data that no longer needs to be in /work but must be retained long term.

We are pleased to announce the fourth Frontera Pathways and Frontera Large Scale Community Partnership (LSCP) allocation tracks will remain open through November 20. Resources available for request include Frontera and its GPU subsystem, as well as the Longhorn GPU resource


Pathways

These are small allocations (between 10,000-250,000 SUs per year) to science teams with a strong scientific justification for access to a leadership-class computing resource, but who have not yet demonstrated code readiness to effectively utilize such a resource.


LSCP

These are allocations (between 25,000-1,000,000 SUs per year, up to 3 years) where we can’t strictly characterize the set of experiments to run within a 12-month allocation period, but that line up with a large team or community, a large instrument, or other large NSF investment.


Detailed descriptions of all four Frontera allocation tracks can be found on the Frontera Allocations web page.


How to Submit an Allocation Request

Please begin by reading the Allocations Policy & Submission Guidelines that provides information regarding who is eligible to apply, minimum and maximum allocation sizes, and an outline of the information that is required to be included in your proposal.


After reading the allocations policy and guidelines, you may determine that a startup allocation would be beneficial to do code performance and benchmarking to be incorporated into your Pathways or LSCP proposal. Instructions for obtaining a Startup allocation are included on the policy & guidelines web page.


Please submit any questions you may have through the TACC Consulting System or feedback form.
